Express Lanes in I-25 South Gap project opening Friday, Dec. 10


DOUGLAS/EL PASO COUNTIES, Colo. (KRDO) -- The Colorado Department of Transportation announced the new Express Lanes on the I-25 South Gap project is opening ahead of schedule. The Express Lanes. between Castle Rock and Monument, will open to drivers Friday, Dec. 10, at 8 a.m.

Because the lanes opened far ahead of schedule, CDOT said tolls will currently be waived during the testing period.

“Opening the Express Lanes early improves safety and travel reliability on the I-25 South Gap corridor,” said Colorado Department of Transportation Executive Director Shoshana Lew. “Commuters will have reliable travel times over the long-term, and experience a vastly improved stretch of I-25 between Monument and Castle Rock. Whether commuting to work or traveling the state, drivers will reach their destinations quicker and safer. We are thrilled to open the Express Lanes a year ahead of schedule and within budget.” 


During the testing period, before tolling is in place, drivers are encouraged to use the Express Lanes free of charge. When using the lanes, drivers are reminded to not cross the solid white lines; enter and exit at the designated areas only, shown with white dotted lines; and obey posted speed limits.

CDOT wants to remind drivers the Express Lanes cannot be used to pass slower-moving vehicles.

In addition to completing the Express Lanes, CDOT has reconstructed five bridges, four wildlife crossings, and laid new pavement. The project is expected to be finished by November 2022.

  1. “CDOT wants to remind drivers the Express Lanes cannot be used to pâss slower-moving vehicles.”
    And therein lies one of the flaws of this system. VERY slow traffic generally occupies the right lane, so everyone else is in the left lane. And some of that traffic only travels at a fairly slow speed, but fast enough for them not to want to be in the slower right lane. So people really need to pâss the left lane traffic without having to commit to a toll or being in the express lane the whole time. Of course, traffic engineers are not well known for having what’s best for drivers in mind when designing these systems.

  2. That’s awesome. Now El Paso County taxpayers get to pay again for the same strip of highway we’ve already paid for through our taxes.

    1. And it didn’t fix the actual problem of the traffic congestion. Just like the addition of the on-ramp lights being added to nearly every intersection getting on I-25. They stated this would fix the congestion, yet driving this road every day, or watching KRDO’s traffic report, one can see this was a fallacy, just more frivolous tax expenditures with little positive outcome for the taxpayers.
